Application filed February 18, 1919. Serial No. 277,791.

To all whom it may concern:

Be it known that I, Jerome W. "WnLoH, a citizen of the United States,residing at Sergeant Blufi, in the county of Woodbury and State of Iowa,have invented certain new and useful Improvements in Concrete StructuresHaving Waterproofing Reln forcements, of which the following is aspecification.

My invention relates to new and useful improvements in reinforcedconcrete structures, the primary ob'ect of my invention being theprovision 0 a waterproofing reinforcement which may be employed inconstructing concrete blocks for building puroses or which may beemployed in the building of monolithic concrete walls.

A still further object of my invention is the provision of a metallicreinforcement in the nature of a partition wall which may be spaced anydesired extent from the weather face of the block or wall in which it isincorporated and which carries a plurality of reinforcing anchoringelements which are embedded in the concrete.

In concrete blocks, the partition wall or main body of the reinforcingelement @X- tends throughout the length and breadth of the block and atits edges is adapted for locking engagement with the reinforcingelements of adjacent blocks so that in a finished structure a thinmetallic wall is in effect provided between an inner and outer wall,although the parts are so firmly united and braced that there can be noseparation between them.

Another object which I have in View is the provision of novel means forlocking the ends of adjacent blocks together, and a novel means forholding the blocks of one course in a wall construction from movementwith respect to the blocks of another course.

Another object which I have in view is the provision of means forinsuring proper positioning of the reinforcing elements duringconstruction of the wall and to provide additional bracing devices forthe wall.

With these and other objects in View, my invention will be more fullydescribed, illustrated in the accompanying drawings, and thenspecifically pointed out in the claims which are attached to and form apart of this specification.

My improved metallic reinforcement includes a rectangular body 10 ofsheet metal of any desired length, breadth and thickness, the length andbreadth of the sheet being substantially that of the block in which itis to be used. Secured along the ends of the body member and againstboth sides thereof are strips of sheet metal 11 which project beyond theends of the body and are bent outwardly away from each other and thenrebent toward each other to provide books 12. As best shown in Fig. 2,the hooks are opposed to each other with their bills spaced somewhatapart. Secured against opposite faces of the body 10 along each sideedge are strips 13 which, at their ends, abut against the inner edges ofthe strips 11 and which project somewhat beyond the edges of the body toprovide channels '14s, as shown in Figs. 3 and 4:. The end strips 11 areformed intermediate their widths with relatively wide slots 15 runningparallel with the ends of the body. Secured over the end strips 11 areouter end strips 16 which terminate at their ends flush with the outeredges of the side strips 13 and which are formed with relatively narrowslots 17 enlarged at one end to provide an opening 18 e ual in Width tothe slots 1 5. These narrow s ots 17, together with their continuations18, are equal in length to the slots 15 and serve as anchoring seats fora number of reinforcing elements 19. Each of these reinforcing elementsincludes a body of sheet metal having its outer end bifurcated and thearms thus formed bent laterally in opposite directions to provideanchoring members 20, as clearly shown in Flgs. 1 and 2 and having itsinner end bent at a right angle, as shown in Fig. 2. Secured to the bodyportion of these strips 19, ad a cent the ends 21, are strips 22 whichhave their free ends bent at right angles, as shown at 23 to lie in theplane of the terminals 21 of the strips. The portions 21 and 23 therebyform seating heads which may be passed through the openings 18 and intothe slots 15, the portions connecting these heads with the remainder ofthe reinforcing element being slidable in the slots 17. By this means, anumber of the reinforcing elements 19 may be applied to the ends of themain reinforcing element or structure 10 at either side.

Extending longitudinally of the body 10 and along both sides and inparallel spaced relation to the side strips 13 are supporting strips ofsheet metal 24 which, at intervals, are out struck to provide pockets 25capable of receiving the terminals 26 of substantially Z-shapedreinforcing elements 27. Each of these elements is in the form of astrip of sheet metal having its end portions bent at right angles to itsintermediate portion. These reinforcing elements 27 are employed onlyalong the upper part of the body 10 and, of course, have their endshooked downwardly into the pockets and their other ends directedupwardly. Somewhat similar reinforcing elements 28 are provided for thelower portion of the body in which the outer ends are bent parallel withthe inner ends so that the outer ends may extend downwardly when theinner ends engage in the pockets. Obviously, any number of pockets maybe provided and a number of reinforcing elements 27 and 28 employed andthe space at which they are positioned may be altered at will.

Extending longitudinally of the body at each side and substantiallymidway of its height, are strips 29 of corrugated sheet metal, thecorrugations of which, together with the body 10, provide a series ofpockets 30. U-shaped reinforcing loops 31, of wire or equivalentmaterial, have their endportions bent into parallel spaced relation in aplane at right angles to the body portion to engage in these pockets 30so that the intermediate or U-shaped portions of the devices 31 willproject at right angles to the main body 10. Any desired number of thesebracing members 31 may be employed at each side of the body 10 butpreferably they are so arranged as to slightly overlap each other, asshown in Figs. 1 and 2 of the drawings.

The above described structure constitutes the reinforcing element ormember proper of a concrete block and in making the block suchreinforcing member is embedded between the front and back walls of theblock with which it is coextensive. The reinforcing structure ispreferably embedded in the block so that its body is located fromone-third to one-half the thickness of the block from the front orweather face of the block, although this location is not absolutelyessential. The block is of such size that the edges of the side strips13 are flush with the upper and lower faces of the block, while thehooks 12 project beyond the ends of the block.

In building a wall from the above described reinforced concrete blocks,the blocks to make up any given course are placed end to end in theusual manner which brings the hooks at the end of one block againstthose at the end of an adjacent block, as clearly shown in Fig. 6 of thedrawings. U-shaped anchoring strips 32 of sheet metal are then appliedin the manner shown in Fig. 6, each locking one of the hooks of oneblock to the abutting hook of the next block and the two togetherholding each other against displacement. These locking members 32 arepreferably embedded in a liquid metal cement which will later set toform a waterproof joint and any suitable form of cement or mortar 33 maybe employed to close the remainder of the joint between the blocks. As ameans for holding the blocks of one course against lateral movement withrespect to the blocks of adjacent courses and also as a means forproviding waterproof horizontal joints between courses, I employ lookingstrips 34 of sheet metal which seat in the alined channels 14 along thetop and bottom edges of the blocks formed between the strips 13 andwhich are set in the same metal cement. A thin layer 35 of cement ormortar is interposed between the courses of blocks.

From the foregoing description, it will be apparent that with any wallconstructed with such reinforced concrete blocks it will be impossiblefor water or moisture to pass through the block asan absolutely watertight metallic partition wall coextensive with the concrete wall isformed by the re inforcing structures and water tight joints betweenthem. At the same time, the various anchoring devices or reinforcinelements 19, 27, 28 and 30 being embed ed in the concrete, positivelybind all the parts together so that the block has greater tensilestrength than any concrete block of corresponding dimensions not havingthe metallic reinforcement.

In Figs. 8 to 10 inclusive, I have illustrated a metallic reinforcementto be employed in the construction of monolithic concrete walls, Thisreinforcement is identical with that previously described, except forcertain additional elements. Anchoring plates 36 are riveted orotherwise Secured against opposite sides of the body 10 at suitablepoints, such as at diametrically opposite portions of the central partof the body, as shown in Fig. 8, and have threaded sockets to receiverod or pipe sections 37 which extend at right angles to the body 10 andwhich, at their ends, are connected by unions 38 with vertical rod orpipe sections 39. These pipe sections, secured to the body as described,greatly increase the strength of the wall, and they may be longer orshorter according to the thickness of the wall. In addition to thesesupplemental anchoring members I provide centering fingers to in theform of strips of sheet metal secured to opposite sides of the loweredge of the body 10 and projecting beyond such edge having pointedterminals 41. The free ends of these centering fingers are adapted tostraddle the upper edge of a subjacent body section to insure bringingthe channels 14: of such sections into alinement with each other toproperly seat the anchoring strips 34:. Of course, in building the wall,the reinforcing elements are assembled and connected with each other asthe work of building the wall progresses, the various anchoring membersbeing applied in each instance just prior to the application of thatlayer of concrete which will embed them.

Although I have illustrated and described my invention in all itsdetails of construction, it will of course be understood that I do notlimit myself to such details but reserve the right to make changes,within the scope of the appended claims, without in the slightest degreedeparting from the spirit of my invention.
